Plain English Summary

Background and study aims
At hospitals across the UK, universities, companies making medicines, and the UK Government are working together to see if existing treatments for other conditions or diseases or new drugs may be used to treat people with COVID-19.
To do this, several treatments will be tested, one at a time, in people with COVID-19. Some treatments act directly against the virus when it gets into the body. Other treatments help the body’s immune system (the natural defence against viral infections) to work better.
As each treatment is tested in people with COVID-19, a group of doctors and researchers will look at the results to see whether it works and how safe it is.
The medicines used will be tested in 2 stages: Stage 1 and Stage 2
Stage 1 will test how safe the medicines are when given with standard-of-care. Stage 1 will also look at whether the medicines work to improve symptoms of COVID-19. The information gathered from Stage 1 will be used to see if the medicines should continue to be tested in Stage 2 of the study.
Stage 2 will continue to look at whether the medicines work when given with standard-of-care and how safe it is. Stage 2 will further look at the effects of the medicines on the disease, such as collecting information on whether symptoms have improved, if care in the intensive care unit is needed, and survival and health status after recovery. In Stage 2, the study doctor and researchers are investigating if the medicines work to lessen the symptoms of COVID-19 or shorten the time people with COVID-19 are ill.

Who can participate?
Patients are being invited to take part in the research study because they have been feeling unwell with symptoms caused by a virus, and their health needs to be looked after in hospital. The virus is called SARS-CoV-2 (severe acute respiratory syndrome-coronavirus 2). The disease that the virus causes in infected people is called COVID-19.

What does the study involve?
Patients participating in the trial will be asked to take part in either Stage 1 or Stage 2 of the study. The patient will have some tests and assessments conducted to check that the study is right for them. If the study is right for the patient, the treatment phase of the study will begin and will last for about 15 days.
The patient will be randomly assigned (by chance) to receive either the study drug with standard-of-care or standard-of-care only.
The patient will have some tests and assessments performed daily while they are in the hospital. These include a check of their health and whether they need oxygen, and taking blood and throat/nose swab samples to check their health. Some of the tests and assessments being done in this study would also be done as part of the standard-of-care for COVID-19, even if they did not participate in this study.
During the treatment period, blood, saliva (spit), or throat/nose swab samples will also be taken for exploratory research.

Once the patient has been discharged from the hospital, they will be asked to come back to the hospital on Day 15 and Day 29, if possible. At these visits, some of the previous tests and assessments will be repeated. If the patient is unable to return to the hospital due to being quarantined or for other safety reasons, some of the tests and assessments may be done by telephone or the hospital may arrange for a home visit by a member of the study team.

After the treatment period, the patient may be asked to return to the hospital on Day 60 (after 2 months) and Day 90 (after 3 months). This is to check how they are doing and if they have had any side effects from the study drug. Additional blood samples may also be taken for exploratory research.
Alternatively, the patient may be contacted by a member of the study team by telephone or they may visit them at home on these days.

What are the possible benefits and risks of participating?
Benefits: Participation in the research will help research efforts to understand COVID-19 and for the development of drugs and tests that could help many other people in the future.
Risks: All medicines may cause some side effects in some people. It is possible that the symptoms will not improve during the study or may even worsen. The study drugs may also involve risks to future health that we currently don’t know about. These will be discussed with participants by the treating doctor.
There are other risks associated with the COVID-19 infection and the use of supplemental oxygen, but they are not specific to this study.

Scientific titleACCORD 2: a multicentre, seamless, Phase 2 adaptive randomisation platform study to assess the efficacy and safety of multiple candidate agents for the treatment of COVID-19 in hospitalised patients
Study acronymCOVID-19 - ACCORD-2
Study hypothesisThe primary hypothesis at Stage 1 is time to response (2-point improvement in the 9-point ordinal scale, live discharge from hospital, or considered fit for discharge, as analysed at Day 29) of the candidate arm is shorter than the SoC.

The primary hypothesis at Stage 2 is time to response (as analysed at Day 29) of the candidate arm is shorter than the SoC.
Ethics approval(s)Approved 24/04/2020 South Central – Oxford C Research Ethics Committee (Level 3, Block B, Whitefriars, Lewins Mead, Bristol, BS1 2NT, UK; +44 (0)207 972 2496; oxfordc.rec@hra.nhs.uk), ref: 20/SC/0201
ConditionCOVID-19 (SARS-CoV-2 infection)
InterventionThe study consists of 2 stages:
• Stage 1 of the study (evaluation/pilot) will evaluate the candidate agents as an add-on to the SoC to assess preliminary safety and efficacy. A patient will be considered to be a responder if they show an improvement of at least 2 points (from randomisation) on a 9-point category ordinal scale, are discharged from hospital, or are considered fit for discharge (a score of 0, 1, or 2 on the ordinal scale), whichever comes first, by Day 29. The time to response will be analysed on Day 29 and used to evaluate if an agent should proceed to Stage 2 of the study. Stage 1 data will additionally be used to determine optimal study endpoints, and the number of patients to enrol into Stage 2 of the study.

• Stage 2 of the study (confirmation) is intended to provide confirmatory data of the identified candidate agents from Stage 1, to fully evaluate disease outcomes, including severe AEs, overall AEs, AESIs, disease-related co-infection complications (eg, pneumonia, septic shock), and overall mortality in an expansion stage. Patients and outcomes from Stage 1 will not form part of Stage 2.

Some candidate agents will still be in Stage 1 of the study at the point where other candidate agents have progressed to Stage 2.

First dose of candidate agent must take place within 72 hours of investigator receipt of laboratory or validated point of care test confirmation of SARS-CoV-2 infection. This may include results from a test that was performed prior to hospital admission if, in the opinion of the Investigator, it is relevant to ongoing COVID-19 infection. Any exceptions to this must be authorised by the Chief Investigator or delegate.

Patients will be randomised to receive one of the candidate agents that is being evaluated at the time of randomisation and whose inclusion/exclusion criteria they meet (as an add-on to SoC) or to a control arm where only SoC is administered.

In each stage of the study, patients will be screened on Day -1 or Day 1, and will remain in the hospital from Day 1 until fit for discharge. Dosing with the candidate agent (as an add-on to SoC) will commence on Day 1. The last day of assessments, while hospitalised, will be on Day 29. An outpatient visit will be conducted on Day 60 (±4 days), with an end-of-study visit conducted on Day 90 (±6 days).

Enrolment of patients will be continuous throughout the study for each candidate agent until the total randomisation number of planned patients for Stage 1 and Stage 2 is achieved. Enrolment under a sub-protocol for a specific candidate agent may also be stopped in the event of success or failure of the candidate agent. The Master Protocol will continue enrolling patients as long as there are candidate agents that are enrolling. It is estimated that up to 1800 patients will participate in the overall study.

Dosage of candidate agents:
Bemcentinib
Bemcentinib will be administered as a 400-mg oral loading dose on Days 1,2,and 3 followed by 200 mg once-daily oral maintenance dose for a total of 15 days. Bemcentinib should be taken once per day.

MEDI3506
MEDI3506 will be administered to participants as a single 300-mg IV dose.

Acalabrutinib
100 mg per day starting on Day 1 and continuing until Day 10.

Zilucoplan
Once-daily subcutaneous injection of 32.4 mg zilucoplan for maximum 15 days.
